This is my first post. I just swapped computers at work from Intel i3 to Intel i5 Windows 7 Acer laptop. My old laptop had 8 Gb RAM and the new one had 4 Gb, so I moved the 8 Gb RAM card to the newer computer. Now, about 3-4 times a day, my screen goes completely non-responsive with Wavy LInes filling the screen (each 'row is no more than the height of the type above "Posting a new Topic in Windows 7"). Our tech guy (a carpenter turned IT guy 4-5 years ago with no previous background--doing a great job) updated my video card thinking that would resolve the problem. It did not. (It has been suggested I reinstall my video card altogether). No noticeable action or activity appears to trigger the crash
